Definitions

  • the invention relates to cosmetic product applicators.
  • Articles are known for applying mascara comprising a mascara reservoir and a cap to which a brush is integrally linked. In the closed position, the brush bathes in the tank. When using, it is best to remove excess mascara from the bristles of the brush.
  • the article includes a wringer at the inlet of the reservoir.
  • the brush comes out of the reservoir loaded with product in particular at the base of the bristles and around the core of the brush.
  • this product is little used for making up the eyelashes.
  • in contact with air it tends to dry on the brush, which may alter the properties of the brush over time and reduce the life of the article.
  • WO 2010/066748 describes a cosmetic product applicator.
  • One aim of the invention is therefore to have greater control over the loading of the applicator with the product.
  • an applicator according to claim 1 is provided according to the invention.
  • the loading of the protuberances with product is limited to an end portion thereof.
  • the eyelashes preferably come into contact during makeup. Consequently, it is ensured that most of the product placed on the applicator is actually used for makeup. This reduces waste. It also reduces the risk of the product drying out on the brush and extends the life of the brush.
  • protuberances according to the invention should be understood as being protuberances having a makeup role.
  • one of the advantages of the mobility of the protuberances and in particular of their ability to extend inside the body of the applicator is that it saves space when the applicator is stored inside the applicator. article, which thus makes it possible to produce such articles with reduced bulk.
  • the bead may in particular be present on a middle portion of the protuberance. It allows the protrusion to carry over the bead a greater amount of product as the protrusion moves from the retracted position to the extended position.
  • the protuberances will for example be hairs, teeth, fingers or other similar reliefs.
  • the applicator is arranged so that at least some of the protuberances extend fully into the body in the retracted position.
  • the applicator is arranged so that all the protuberances extend fully into the body in the retracted position.
  • the size of the applicator is further reduced, in particular when the latter is stored inside the article.
  • the protuberances form groups of protuberances extending in the same plane perpendicular to the axis, the protuberances of each group being interconnected by one end of the protuberances internal to the body.
  • connection between the internal ends of the protuberances of the same group can be done in different ways. This connection can for example be made directly between the ends. This connection can also be done indirectly. In this case, the ends of the protuberances of the same group are each linked to a central element.
  • the groups of protrusions exhibit a conformation other than a star conformation.
  • the choice of configurations that can be given to the applicator is thus increased.
  • the body comprises stacked disks.
  • discs can be linked together by various known means. They can for example be glued, welded, or nested. Each disc may for example have on one face one or more reliefs and on its other face one or more cavities. The relief (s) of the disc fit into the cavity (s) of a contiguous disc.
  • the groups extend between the disks.
  • the body has cells for receiving the protuberances, at least part of the cells having a free volume capable of receiving product when the protuberance is in the retracted position in the cell.
  • the free volume is therefore chosen, so that these cells receive larger or smaller quantities of cosmetic product.
  • the volume of the latter can be increased, and vice versa when it is desired to reduce the quantity, or even to make it zero.
  • the bead is preferably present on the portion of the protuberance located inside the cell in the retracted position. It therefore makes it possible to delimit a free volume of the cell, capable of receiving product when the protuberance is in the retracted position in the cell.
  • the volume of the cells as well as the position of the bead on the protuberance are all characteristics allowing the predetermination of the quantity of cosmetic product which will be loaded on the protuberance. For example, if it is desired that only a small part of it is loaded with mascara, and therefore that the loading of product is low, the bead can be positioned near its free end and thus reduce the free volume, and vice versa if we want more to be loaded with mascara.
  • the bead can act as a guide for the protuberance within the cell by pressing against the internal face of the latter.
  • the applicator is arranged so that the free volume extends around the protuberance.
  • the protrusions may be in an elbow or "S" conformation.
  • the non-rectilinear conformation in the retracted position results in reduced bulk.
  • the article comprises a case, the applicator being fixed to the case while being movable relative to the case between a retracted position and an extended position in which it extends more out of the case than it does. in the retracted position.
  • the article is of the “pen” type, that is to say that the applicator and the reservoir are not separated during use.
  • This embodiment has the advantage of facilitating use by the user, since the latter can have a free hand.
  • the article is arranged so that the applicator moves from the retracted position to the extended position following a path parallel to a direction. longitudinal section.
  • the article comprises a member capable of controlling a passage of the applicator from the retracted position to the extended position and a passage of the protuberances from the retracted position to the extended position.
  • the member is arranged to control the passage of the protuberances from the retracted position to the extended position only after the passage of the applicator from the retracted position to the extended position.
  • the article comprises a reservoir of cosmetic product.
  • the article comprises means for applying product to the applicator when the applicator is in the case.
  • the article comprises means for applying product to the applicator when the protuberances are in the retracted position.
  • the quantity of product delivered to the protuberances is reduced and this quantity can more easily be reduced to that just necessary to ensure a good makeup result without wasting product.
  • the cosmetic product is mascara.
  • the cosmetic product here is mascara for making up the eyelashes.
  • Item 50 includes a "pen” type case. It has a generally elongated shape with an axis 51 with symmetry of revolution about this axis.
  • the case has an outer face 52 of generally cylindrical shape with a circular section in a plane perpendicular to the axis 51.
  • the case externally comprises two parts 47, 48 mounted to be movable in rotation with respect to one another coaxially about the axis 51.

  • the disks 2 are in this case 26 in number, this number not being limiting of course.
  • the body also comprises a cap 5 terminating the stack of disks at one end of the latter opposite the support. The outer face of the body is therefore formed by that of the support 1, that of the discs 2 and that of the cap 5.
  • the brush includes protuberances which in this case are flexible bristles 3. But they could also be teeth or fingers, which could be relatively rigid.
  • the brush may have a configuration in which the bristles 3 extend entirely inside the body 1 without protruding from the external face of the latter and a configuration in which the bristles project from this face.
  • the figures 4A to 4C show in detail a section of the applicator at the level of any two consecutive discs 2.
  • the discs 2 are nested one inside the other. Each disc comprises for this on one of its faces pads 14, here four in number and on its opposite face cavities in the same number, intended to receive the respective pads of the contiguous disc which follows it in succession.
  • the discs are thus precisely positioned and fixed relative to each other and prevented from rotating relative to each other around the axis or from sliding relative to each other in a direction perpendicular to this axis. Stacked disks can be linked by different means.
  • the discs are glued to each other by their surfaces in contact. The same is true for the cap 5 which is glued to the last disc of the stack and for the support 1 which is glued to the first disc of the stack. A rigid assembly is thus formed, forming the body.
  • the disks 2 are configured so that two contiguous disks define at their interface cells 37 which here are eight in number.
  • Each cell has in this case a frustoconical shape having an axis 53 having an orientation perpendicular to the main axis 51.
  • the widest section of the truncated cone is located at the level of the external face of the body.
  • Each cell 37 has a circular section in a plane perpendicular to its axis 53.
  • the cells have a radial arrangement around the axis 51 and are regularly distributed around the latter.
  • Each cell is formed half by one of the discs and half by the other disc.
  • Each face of one of the discs therefore has recesses in the form of semi-truncated cones. radials.
  • the recesses of one of the faces of each disc are angularly offset around the axis 51 relative to those of the other face. In fact, otherwise, a very reduced thickness would be obtained for the disc at the level of the bottom of the recesses.
  • the term “crown” denotes the groups of cells extending in the same plane perpendicular to the axis 51.
  • the angular offset of the recesses of each disc causes that of the cells in two consecutive rings of cells. Taking into account the number of cells in each ring, this offset is in this case a 16th turn.
  • the discs have a recess 39 at their center into which the cells 37 open out.
  • each cell 37 receives one bristle 3 and only one so that the bristles and the cells are in the same number.
  • the bristles 3 form rings comprising eight bristles associated with the same plane perpendicular to the axis 51.
  • the bristles extend all around the axis 51, some being diametrically opposed on either side of the axis.
  • the bristles form rows parallel to the axis. The rows are evenly distributed around the axis and the bristles evenly spaced in each row.
  • each hair has a relief in the form of a bead 13, as shown in particular on figure 4A .
  • the bead has a flat face on the side of the bead directed towards the free end of the bristle.
  • the bead extends in a middle portion of the bristle and is therefore located at a distance from each of its ends.
  • the bristles 3 of each crown form a group in which the bristles are attached to one another, here by an internal end of the bristles.
  • the group is given a star configuration visible in particular on the figure 4A .
  • FIGS 4A to 4C between two consecutive discs is interposed a group of bristles of this type so that the bristles are housed in the respective cells.

  • the hairs extend entirely inside the body 1.
  • the bristles 3 protrude out of the body with reference to the radial direction to the axis 51, over a major part of the length of each bristle. It can therefore be seen that the applicator is arranged so that each free end of the bristle follows a path transverse or perpendicular to the longitudinal axis 51 of the applicator from the retracted position to the extended position.

  • the bead In the extended position, shown for example on figure 4B , the bead extends in protrusion of the face of the body. The volume of makeup product which filled the volume of the cell located above the bead has therefore been washed away entirely and is now entirely outside the body.

This has the advantage of not requiring the bristles to come out of their socket when they are in the retracted position and of reducing the space required for storing the applicator in the case. To this end, the central space of the discs is provided to be large enough to receive the inner end section of the bristles which is lying parallel to the axis 51.

Description

L'invention concerne les applicateurs de produit cosmétique.The invention relates to cosmetic product applicators.

On connaît des articles pour l'application de mascara comprenant un réservoir de mascara et un capuchon auquel est liée solidairement une brosse. En position fermée, la brosse baigne dans le réservoir. Lors de l'utilisation, il est préférable d'évacuer l'excès de mascara présent au niveau des poils de la brosse. Pour cela, l'article comprend un essoreur au niveau de l'entrée du réservoir.Articles are known for applying mascara comprising a mascara reservoir and a cap to which a brush is integrally linked. In the closed position, the brush bathes in the tank. When using, it is best to remove excess mascara from the bristles of the brush. For this, the article includes a wringer at the inlet of the reservoir.

De tels articles présentent des inconvénients.Such articles have drawbacks.

La brosse sort du réservoir chargée en produit notamment à la base des poils et autour de l'âme de la brosse. En pratique, ce produit sert peu pour le maquillage des cils. De plus, au contact de l'air, il tend à sécher sur la brosse, ce qui risque d'altérer les propriétés de la brosse à terme et de réduire la durée de vie de l'article. On comprend que le produit en question qui ne sert pas pour le maquillage est gaspillé en définitive.The brush comes out of the reservoir loaded with product in particular at the base of the bristles and around the core of the brush. In practice, this product is little used for making up the eyelashes. In addition, in contact with air, it tends to dry on the brush, which may alter the properties of the brush over time and reduce the life of the article. We understand that the product in question which is not used for makeup is ultimately wasted.

WO 2010/066748 décrit un applicateur de produit cosmétique. WO 2010/066748 describes a cosmetic product applicator.

Un but de l'invention est donc maîtriser davantage le chargement de l'applicateur avec le produit.One aim of the invention is therefore to have greater control over the loading of the applicator with the product.

A cet effet, on prévoit selon l'invention un applicateur selon la revendication 1.To this end, an applicator according to claim 1 is provided according to the invention.

Ainsi, on limite le chargement des protubérances en produit à une portion terminale de celles-ci. Or c'est avec cette partie des protubérances que les cils viennent en contact de préférence lors du maquillage. Par conséquent, on fait en sorte que la plus grande partie du produit disposé sur l'applicateur serve effectivement pour le maquillage. Cela réduit le gaspillage. Cela réduit aussi les risques de séchage du produit sur la brosse et allonge la durée de vie de cette dernière.Thus, the loading of the protuberances with product is limited to an end portion thereof. Now, it is with this part of the protuberances that the eyelashes preferably come into contact during makeup. Consequently, it is ensured that most of the product placed on the applicator is actually used for makeup. This reduces waste. It also reduces the risk of the product drying out on the brush and extends the life of the brush.

Les protubérances selon l'invention doivent être comprises comme étant des protubérances ayant un rôle de maquillage.The protuberances according to the invention should be understood as being protuberances having a makeup role.

Par ailleurs, un des avantages de la mobilité des protubérances et notamment de leur capacité à s'étendre à l'intérieur du corps de l'applicateur est de permettre un gain de place lorsque l'applicateur est rangé à l'intérieur de l'article, ce qui permet ainsi de réaliser de tels articles avec un encombrement réduit.Moreover, one of the advantages of the mobility of the protuberances and in particular of their ability to extend inside the body of the applicator is that it saves space when the applicator is stored inside the applicator. article, which thus makes it possible to produce such articles with reduced bulk.

Le bourrelet peut notamment être présent sur une portion médiane de la protubérance. Il permet à la protubérance d'emporter au-dessus du bourrelet une plus grande quantité de produit lorsque la protubérance passe de la position rétractée à la position étendue.The bead may in particular be present on a middle portion of the protuberance. It allows the protrusion to carry over the bead a greater amount of product as the protrusion moves from the retracted position to the extended position.

Les protubérances seront par exemple des poils, des dents, des doigts ou d'autres reliefs analogues.The protuberances will for example be hairs, teeth, fingers or other similar reliefs.

On peut prévoir que chaque extrémité libre suit une trajectoire sensiblement perpendiculaire à un axe longitudinal de l'applicateur.Provision can be made for each free end to follow a path substantially perpendicular to a longitudinal axis of the applicator.

On peut prévoir aussi que l'angle formé par la trajectoire et l'axe longitudinal de l'applicateur est compris entre 60° et 120°.Provision can also be made for the angle formed by the trajectory and the longitudinal axis of the applicator to be between 60 ° and 120 °.

Avantageusement, l'applicateur est agencé de sorte qu'au moins certaines des protubérances s'étendent intégralement dans le corps en position rétractée.Advantageously, the applicator is arranged so that at least some of the protuberances extend fully into the body in the retracted position.

Avantageusement encore, l'applicateur est agencé de sorte que toutes les protubérances s'étendent intégralement dans le corps en position rétractée.Again advantageously, the applicator is arranged so that all the protuberances extend fully into the body in the retracted position.

Ainsi, on réduit encore l'encombrement de l'applicateur, notamment lorsque celui-ci est rangé à l'intérieur de l'article.Thus, the size of the applicator is further reduced, in particular when the latter is stored inside the article.

Dans un mode de réalisation, les protubérances forment des groupes de protubérances s'étendant dans un même plan perpendiculaire à l'axe, les protubérances de chaque groupe étant reliées entre elles par une extrémité des protubérances interne au corps.In one embodiment, the protuberances form groups of protuberances extending in the same plane perpendicular to the axis, the protuberances of each group being interconnected by one end of the protuberances internal to the body.

La liaison entre les extrémités internes des protubérances d'un même groupe peut se faire de différentes manières. Cette liaison peut par exemple être réalisée de manière directe entre les extrémités. Cette liaison peut également se faire de manière indirecte. Dans ce cas, les extrémités des protubérances d'un même groupe sont chacune liées à un élément central.The connection between the internal ends of the protuberances of the same group can be done in different ways. This connection can for example be made directly between the ends. This connection can also be done indirectly. In this case, the ends of the protuberances of the same group are each linked to a central element.

On peut notamment avoir une conformation dans laquelle ces protubérances s'étendent radialement avec un espacement égal entre les protubérances. Cette conformation présente l'avantage de favoriser une répartition uniforme du produit tout autour du corps de l'applicateur.In particular, it is possible to have a conformation in which these protuberances extend radially with equal spacing between the protuberances. This conformation has the advantage of promoting a uniform distribution of the product all around the body of the applicator.

On peut prévoir que chaque groupe présente une configuration en étoile.Provision can be made for each group to have a star configuration.

Alternativement, les groupes de protubérances présentent une conformation autre qu'une conformation en étoile. On augmente ainsi le choix des configurations que l'on peut donner à l'applicateur.Alternatively, the groups of protrusions exhibit a conformation other than a star conformation. The choice of configurations that can be given to the applicator is thus increased.

De préférence, le corps comprend des disques empilés.Preferably, the body comprises stacked disks.

Il s'agit d'un moyen commode de réaliser le corps de l'applicateur. Ces disques peuvent être liés entre eux par différents moyens connus. Ils peuvent par exemple être collés, soudés, ou emboîtés. Chaque disque peut par exemple posséder sur une face un ou plusieurs reliefs et sur son autre face une ou plusieurs cavités. Le ou les reliefs du disque viennent s'emboîter dans la ou les cavités d'un disque contigu.This is a convenient way to make the body of the applicator. These discs can be linked together by various known means. They can for example be glued, welded, or nested. Each disc may for example have on one face one or more reliefs and on its other face one or more cavities. The relief (s) of the disc fit into the cavity (s) of a contiguous disc.

Avantageusement, les groupes s'étendent entre les disques.Advantageously, the groups extend between the disks.

De préférence, le corps présente des alvéoles de réception des protubérances, au moins une partie des alvéoles présentant un volume libre apte à recevoir du produit lorsque la protubérance est en position rétractée dans l'alvéole.Preferably, the body has cells for receiving the protuberances, at least part of the cells having a free volume capable of receiving product when the protuberance is in the retracted position in the cell.

En choisissant le volume des alvéoles, on choisit donc le volume libre, afin que ces alvéoles reçoivent des quantités plus ou moins grandes de produit cosmétique. Par exemple, si on souhaite augmenter la quantité de produit chargée dans l'alvéole, on peut augmenter le volume de celle-ci, et inversement lorsqu'on souhaite diminuer la quantité, voire la rendre nulle.By choosing the volume of the cells, the free volume is therefore chosen, so that these cells receive larger or smaller quantities of cosmetic product. Through For example, if it is desired to increase the quantity of product loaded into the cell, the volume of the latter can be increased, and vice versa when it is desired to reduce the quantity, or even to make it zero.

Par ailleurs, en présence des alvéoles, le bourrelet est présent de préférence sur la portion de la protubérance située à l'intérieur de l'alvéole en position rétractée. Il permet donc de délimiter un volume libre de l'alvéole, apte à recevoir du produit lorsque la protubérance est en position rétractée dans l'alvéole. Le volume des alvéoles ainsi que la position du bourrelet sur la protubérance sont autant de caractéristiques permettant la prédétermination de la quantité de produit cosmétique qui sera chargée sur la protubérance. Par exemple, si on souhaite que seule une petite partie de celle-ci soit chargée en mascara, et donc que le chargement en produit soit faible, on peut positionner le bourrelet près de son extrémité libre et réduire ainsi le volume libre, et inversement si on souhaite qu'une plus grande partie soit chargée en mascara. En outre, le bourrelet peut jouer un rôle de guide pour la protubérance au sein de l'alvéole par appui contre la face interne de cette dernière.Furthermore, in the presence of the cells, the bead is preferably present on the portion of the protuberance located inside the cell in the retracted position. It therefore makes it possible to delimit a free volume of the cell, capable of receiving product when the protuberance is in the retracted position in the cell. The volume of the cells as well as the position of the bead on the protuberance are all characteristics allowing the predetermination of the quantity of cosmetic product which will be loaded on the protuberance. For example, if it is desired that only a small part of it is loaded with mascara, and therefore that the loading of product is low, the bead can be positioned near its free end and thus reduce the free volume, and vice versa if we want more to be loaded with mascara. In addition, the bead can act as a guide for the protuberance within the cell by pressing against the internal face of the latter.

On peut par exemple prévoir que les disques formant le corps présentent des faces opposées agencées de telle sorte que l'empilement de ces disques forme les alvéoles dans lesquelles les groupes de protubérances viennent se loger.Provision can for example be made for the discs forming the body to have opposite faces arranged such that the stack of these discs forms the cells in which the groups of protuberances are received.

Avantageusement l'applicateur est agencé de sorte que le volume libre s'étend autour de la protubérance.Advantageously, the applicator is arranged so that the free volume extends around the protuberance.

On peut prévoir que l'applicateur est agencé de sorte qu'au moins certaines des protubérances sont dans une conformation non-rectiligne en position rétractée.Provision can be made for the applicator to be arranged so that at least some of the protuberances are in a non-rectilinear conformation in the retracted position.

Par exemple, au moins certaines des protubérances peuvent être dans une conformation coudée ou en « S ». La conformation non-rectiligne en position rétractée engendre un encombrement réduit.For example, at least some of the protrusions may be in an elbow or "S" conformation. The non-rectilinear conformation in the retracted position results in reduced bulk.

On peut prévoir qu'au moins certaines des protubérances occupent des positions diamétralement opposées de part et d'autre de l'axe.Provision can be made for at least some of the protuberances to occupy diametrically opposed positions on either side of the axis.

On prévoit également selon l'invention un article de produit cosmétique qui comprend un applicateur selon l'invention.There is also provided according to the invention an article of cosmetic product which comprises an applicator according to the invention.

De préférence, l'article comprend un étui, l'applicateur étant fixé à l'étui en étant mobile par rapport à l'étui entre une position rentrée et une position sortie dans laquelle il s'étend davantage hors de l'étui qu'en position rentrée.Preferably, the article comprises a case, the applicator being fixed to the case while being movable relative to the case between a retracted position and an extended position in which it extends more out of the case than it does. in the retracted position.

Ainsi, l'article est de type « stylo », c'est-à-dire que l'applicateur et le réservoir ne sont pas séparés lors de l'utilisation. Ce mode de réalisation présentant l'avantage de faciliter l'utilisation par l'utilisateur, puisque celui-ci peut avoir une main libre.Thus, the article is of the “pen” type, that is to say that the applicator and the reservoir are not separated during use. This embodiment has the advantage of facilitating use by the user, since the latter can have a free hand.

Dans un mode de réalisation, l'article est agencé de sorte que l'applicateur passe de la position rentrée à la position sortie suivant une trajectoire parallèle à une direction longitudinale de l'article.In one embodiment, the article is arranged so that the applicator moves from the retracted position to the extended position following a path parallel to a direction. longitudinal section.

Avantageusement, l'article comprend un organe apte à commander un passage de l'applicateur de la position rentrée à la position sortie et un passage des protubérances de la position rétractée à la position étendue.Advantageously, the article comprises a member capable of controlling a passage of the applicator from the retracted position to the extended position and a passage of the protuberances from the retracted position to the extended position.

Avantageusement, l'organe est agencé pour commander le passage des protubérances de la position rétractée à la position étendue seulement après le passage de l'applicateur de la position rentrée à la position sortie.Advantageously, the member is arranged to control the passage of the protuberances from the retracted position to the extended position only after the passage of the applicator from the retracted position to the extended position.

Ainsi on peut réduire les dimensions d'un orifice de sortie de l'étui pour l'applicateur ainsi que le volume général de l'article. Cela permet également de contrôler plus facilement la quantité de mascara qui est prise par la brosse.Thus it is possible to reduce the dimensions of an outlet orifice of the case for the applicator as well as the general volume of the article. It also makes it easier to control the amount of mascara that is taken up by the brush.

De préférence, l'article comprend un réservoir de produit cosmétique.Preferably, the article comprises a reservoir of cosmetic product.

Avantageusement, l'article comprend des moyens pour appliquer du produit sur l'applicateur lorsque l'applicateur est dans l'étui.Advantageously, the article comprises means for applying product to the applicator when the applicator is in the case.

Ainsi on évite d'exposer directement le contenu du réservoir à l'air ambiant, ce qui permet de réduire le séchage du produit du réservoir.This avoids directly exposing the contents of the tank to the ambient air, which makes it possible to reduce the drying of the product in the tank.

De préférence aussi, l'article comprend des moyens pour appliquer du produit sur l'applicateur lorsque les protubérances sont en position rétractée.Also preferably, the article comprises means for applying product to the applicator when the protuberances are in the retracted position.

Ainsi on réduit la quantité de produit délivrée sur les protubérances et on peut plus facilement réduire cette quantité à celle juste nécessaire pour assurer un bon résultat de maquillage sans gaspillage de produit.Thus, the quantity of product delivered to the protuberances is reduced and this quantity can more easily be reduced to that just necessary to ensure a good makeup result without wasting product.

Un tel réservoir peut par exemple être un réservoir comprenant :

  • une paroi externe,
  • une paroi interne s'étendant entre la paroi externe et un axe principal du réservoir, et
  • du produit cosmétique, le produit se trouvant exclusivement du côté d'une face de la paroi interne orientée vers la paroi externe.
Such a reservoir can for example be a reservoir comprising:
  • an external wall,
  • an inner wall extending between the outer wall and a main axis of the reservoir, and
  • of the cosmetic product, the product located exclusively on the side of a face of the internal wall oriented towards the external wall.

D'autres réservoirs peuvent être envisagés.Other reservoirs can be considered.

De manière préférée, le produit cosmétique est du mascara.Preferably, the cosmetic product is mascara.

Nous allons maintenant présenter un mode de réalisation de l'article 50 selon l'invention en référence aux figures 1 à 12C. Le produit cosmétique est ici du mascara pour le maquillage des cils.We will now present an embodiment of article 50 according to the invention with reference to figures 1 to 12C . The cosmetic product here is mascara for making up the eyelashes.

L'article 50 comprend un étui de type « stylo ». Il présente une forme générale allongée d'axe 51 à symétrie de révolution autour de cet axe. L'étui présente une face externe 52 de forme générale cylindrique à section circulaire dans un plan perpendiculaire à l'axe 51.Item 50 includes a "pen" type case. It has a generally elongated shape with an axis 51 with symmetry of revolution about this axis. The case has an outer face 52 of generally cylindrical shape with a circular section in a plane perpendicular to the axis 51.

L'étui comprend extérieurement deux parties 47, 48 montées mobiles à rotation l'une par rapport à l'autre coaxialement autour de l'axe 51. Dans la suite, et par commodité, on désignera la partie 48 comme la partie fixe et la partie 47 comme la partie mobile.The case externally comprises two parts 47, 48 mounted to be movable in rotation with respect to one another coaxially about the axis 51. In the following, and for convenience, part 48 will be designated as the fixed part and the part. part 47 as the moving part.

La brosseThe brush

Les figures 2A à 2D représentent l'applicateur de mascara 11 de l'article. Il s'agit ici d'une brosse.The figures 2A to 2D represent the mascara applicator 11 of the article. It is here of a brush.

La brosse comprend un corps 1 présentant une face externe de forme cylindrique à section circulaire dans un plan perpendiculaire à l'axe 51. Le corps comprend un support allongé 1 et des disques 2, tous identiques entre eux et empilés coaxialement avec le support pour le prolonger à une extrémité du support. Les disques 2 sont en l'espèce au nombre de 26, ce nombre n'étant pas limitatif bien entendu. Le corps comprend également un chapeau 5 terminant l'empilement des disques à une extrémité de ce dernier opposée au support. La face externe du corps est donc formée par celle du support 1, celle des disques 2 et celle du chapeau 5.The brush comprises a body 1 having an outer face of cylindrical shape with a circular section in a plane perpendicular to the axis 51. The body comprises an elongated support 1 and discs 2, all identical to each other and stacked coaxially with the support for the brush. extend to one end of the support. The disks 2 are in this case 26 in number, this number not being limiting of course. The body also comprises a cap 5 terminating the stack of disks at one end of the latter opposite the support. The outer face of the body is therefore formed by that of the support 1, that of the discs 2 and that of the cap 5.

La brosse comprend des protubérances qui sont en l'espèce des poils souples 3. Mais il pourrait s'agir aussi de dents ou de doigts, qui pourraient être relativement rigides.The brush includes protuberances which in this case are flexible bristles 3. But they could also be teeth or fingers, which could be relatively rigid.

La brosse peut avoir une configuration dans laquelle les poils 3 s'étendent tout entiers à l'intérieur du corps 1 sans dépasser de la face externe de ce dernier et une configuration dans laquelle les poils s'étendent en saillie de cette face.The brush may have a configuration in which the bristles 3 extend entirely inside the body 1 without protruding from the external face of the latter and a configuration in which the bristles project from this face.

Les figures 4A à 4C représentent en détail un tronçon de l'applicateur au niveau de deux disques consécutifs quelconques 2.The figures 4A to 4C show in detail a section of the applicator at the level of any two consecutive discs 2.

Les disques 2 sont emboîtes les uns dans les autres. Chaque disque comprend pour cela sur l'une de ses faces des plots 14, ici au nombre de quatre et sur sa face opposée des cavités en même nombre, destinées à recevoir les plots respectifs du disque contigu qui le suit dans la succession. Les disques sont ainsi précisément positionnés et fixés les uns par rapport aux autres et empêchés de tourner les uns par rapport aux autres autour de l'axe ou de coulisser les uns par rapport aux autres suivant une direction perpendiculaire à cet axe. Les disques empilés peuvent être liés par différentes moyens. Ici les disques sont collés les uns aux autres par leurs faces en contact. Il en est de même pour le chapeau 5 qui est collé au dernier disque de l'empilement et pour le support 1 qui est collé au premier disque de l'empilement. On constitue ainsi un ensemble rigide formant le corps.The discs 2 are nested one inside the other. Each disc comprises for this on one of its faces pads 14, here four in number and on its opposite face cavities in the same number, intended to receive the respective pads of the contiguous disc which follows it in succession. The discs are thus precisely positioned and fixed relative to each other and prevented from rotating relative to each other around the axis or from sliding relative to each other in a direction perpendicular to this axis. Stacked disks can be linked by different means. Here the discs are glued to each other by their surfaces in contact. The same is true for the cap 5 which is glued to the last disc of the stack and for the support 1 which is glued to the first disc of the stack. A rigid assembly is thus formed, forming the body.

Les disques 2 sont configurés de sorte que deux disques contigus définissent à leur interface des alvéoles 37 qui sont ici au nombre de huit. Chaque alvéole a en l'espèce une forme tronconique ayant un axe 53 présentant une orientation perpendiculaire à l'axe principal 51. La section la plus large du tronc de cône se situe au niveau de la face externe du corps. Chaque alvéole 37 a une section circulaire dans un plan perpendiculaire à son axe 53. Les alvéoles présentes une disposition radiale autour de l'axe 51 et sont régulièrement réparties autour de ce dernier. Chaque alvéole est formée pour moitié par l'un des disques et pour moitié par l'autre disque. Chaque face de l'un des disques présente donc des évidements en forme de demi-troncs de cône radiaux.The disks 2 are configured so that two contiguous disks define at their interface cells 37 which here are eight in number. Each cell has in this case a frustoconical shape having an axis 53 having an orientation perpendicular to the main axis 51. The widest section of the truncated cone is located at the level of the external face of the body. Each cell 37 has a circular section in a plane perpendicular to its axis 53. The cells have a radial arrangement around the axis 51 and are regularly distributed around the latter. Each cell is formed half by one of the discs and half by the other disc. Each face of one of the discs therefore has recesses in the form of semi-truncated cones. radials.

Afin de ne pas fragiliser les disques, les évidements de l'une des faces de chaque disque sont décalés angulairement autour de l'axe 51 par rapport à ceux de l'autre face. En effet, dans le cas contraire, on obtiendrait une épaisseur très réduite pour le disque au niveau du fond des évidements. On désigne par « couronne » les groupes d'alvéoles s'étendant dans un même plan perpendiculaire à l'axe 51. Le décalage angulaire des évidements de chaque disque entraîne celui des alvéoles dans deux couronnes d'alvéoles consécutives. Compte tenu du nombre d'alvéoles dans chaque couronne, ce décalage est en l'espèce d'un 16e de tour.In order not to weaken the discs, the recesses of one of the faces of each disc are angularly offset around the axis 51 relative to those of the other face. In fact, otherwise, a very reduced thickness would be obtained for the disc at the level of the bottom of the recesses. The term “crown” denotes the groups of cells extending in the same plane perpendicular to the axis 51. The angular offset of the recesses of each disc causes that of the cells in two consecutive rings of cells. Taking into account the number of cells in each ring, this offset is in this case a 16th turn.

Les disques présentent un évidement 39 en leur centre dans lequel débouchent les alvéoles 37.The discs have a recess 39 at their center into which the cells 37 open out.

Dans ce mode de réalisation, chaque alvéole 37 reçoit un poil 3 et un seul de sorte que les poils et les alvéoles sont en même nombre. Ainsi, tout comme les alvéoles 37, les poils 3 forment des couronnes comprenant huit poils associés à un même plan perpendiculaire à l'axe 51.In this embodiment, each cell 37 receives one bristle 3 and only one so that the bristles and the cells are in the same number. Thus, just like the cells 37, the bristles 3 form rings comprising eight bristles associated with the same plane perpendicular to the axis 51.

On voit que les poils s'étendent tout autour de l'axe 51, certains étant diamétralement opposés de part et d'autre de l'axe. Les poils forment des rangées parallèles à l'axe. Les rangées sont régulièrement réparties autour de l'axe et les poils régulièrement espacés dans chaque rangée.It can be seen that the bristles extend all around the axis 51, some being diametrically opposed on either side of the axis. The bristles form rows parallel to the axis. The rows are evenly distributed around the axis and the bristles evenly spaced in each row.

Dans ce mode de réalisation, chaque poil présente un relief sous la forme d'un bourrelet 13, comme représenté notamment à la figure 4A. Le bourrelet présente en l'espèce une face plane du côté du bourrelet dirigé vers l'extrémité libre du poil. Le bourrelet s'étend dans une portion médiane du poil et se trouve donc à distance de chacune de ses extrémités.In this embodiment, each hair has a relief in the form of a bead 13, as shown in particular on figure 4A . In this case, the bead has a flat face on the side of the bead directed towards the free end of the bristle. The bead extends in a middle portion of the bristle and is therefore located at a distance from each of its ends.

Dans le présent exemple, les poils 3 de chaque couronne forment un groupe dans lequel les poils sont fixés les uns aux autres, ici par une extrémité interne des poils. De la sorte, on donne au groupe une configuration en étoile visible notamment sur la figure 4A. Comme on le voit sur les figures 4A à 4C, entre deux disques consécutifs est interposé un groupe de poils de ce type de telle sorte que les poils sont logés dans les alvéoles respectives.In the present example, the bristles 3 of each crown form a group in which the bristles are attached to one another, here by an internal end of the bristles. In this way, the group is given a star configuration visible in particular on the figure 4A . As seen on figures 4A to 4C , between two consecutive discs is interposed a group of bristles of this type so that the bristles are housed in the respective cells.

Les poils peuvent être dans n'importe quelle matière utilisée habituellement dans la constitution des brosses d'applicateurs de mascara. Les poils d'un même groupe de protubérances peuvent être de matières différentes. En outre, les poils situés à des étages différents n'ont pas forcément la même composition. Un même poil peut également être composé de plusieurs matières différentes. Par exemple, un poil peut être bi-matière et posséder ainsi un noyau d'une certaine matière et une paroi externe d'une autre matière. Les poils ne sont pas forcément faits d'une matière plastique. Par exemple, les poils peuvent être composés d'une matière naturelle telle que des fibres naturelles.The bristles can be in any material commonly used in the constitution of mascara applicator brushes. The bristles of the same group of protuberances can be of different materials. In addition, the bristles located on different floors do not necessarily have the same composition. The same hair can also be made up of several different materials. For example, a pile can be bi-material and thus have a core of a certain material and an outer wall of another material. The bristles are not necessarily made of plastic. Through For example, the bristles can be composed of a natural material such as natural fibers.

Chaque groupe de poils comprend une bague centrale 12 à laquelle sont liés les poils. L'article comprend une tige rectiligne 4 formant un actionneur. La bague 12 présente une ouverture 15 en son centre permettant ainsi le passage de l'actionneur 4 à travers chaque bague. Toutes les bagues sont ainsi enfilées sur l'actionneur et sont en butée les unes contre les autres suivant la direction de l'axe. Ainsi, la partie centrale 12 d'un groupe de poils 10 d'un étage donné de l'applicateur est en contact avec la partie centrale du groupe de poils de l'étage supérieur et/ou inférieur, cela que les protubérances soient en position rétractée ou en saillie comme on le verra plus loin. L'actionneur 4 comprend à son extrémité terminale libre un organe 40 de blocage axial des bagues sur l'actionneur.Each group of bristles comprises a central ring 12 to which the bristles are bonded. The article comprises a rectilinear rod 4 forming an actuator. The ring 12 has an opening 15 in its center thus allowing the passage of the actuator 4 through each ring. All the rings are thus threaded onto the actuator and are in abutment against each other in the direction of the axis. Thus, the central part 12 of a group of bristles 10 of a given stage of the applicator is in contact with the central part of the group of bristles of the upper and / or lower stage, that that the protuberances are in position. retracted or protruding as will be seen later. The actuator 4 comprises at its free end end a member 40 for axially locking the rings on the actuator.

L'actionneur 4 est monté coulissant dans le corps 1 suivant la direction de l'axe 51 de façon à faire passer les poils de l'applicateur d'une position rétractée à une position étendue et inversement. L'actionneur 4 comprend une surépaisseur 8 et le support 1 un épaulement 41 aptes à coopérer avec cette surépaisseur pour déterminer l'extrémité de fin de course du mouvement de l'actionneur dans le corps associé à la position rétractée. Un agencement est prévu par ailleurs pour limiter la course de l'actionneur dans l'autre sens.The actuator 4 is slidably mounted in the body 1 in the direction of the axis 51 so as to cause the bristles of the applicator to pass from a retracted position to an extended position and vice versa. The actuator 4 comprises an extra thickness 8 and the support 1 a shoulder 41 able to cooperate with this extra thickness to determine the end of travel limit of the movement of the actuator in the body associated with the retracted position. An arrangement is also provided to limit the stroke of the actuator in the other direction.

Dans la position rétractée, visible notamment aux figures 2A et 3A, les poils s'étendent tout entier à l'intérieur du corps 1. Dans la position étendue visible notamment aux figures 2B et 3B, les poils 3 s'étendent en saillie hors du corps par référence à la direction radiale à l'axe 51, sur une majeure partie de la longueur de chaque poil. On voit donc que l'applicateur est agencé de sorte que chaque extrémité libre de poil suit une trajectoire transversale ou perpendiculaire à l'axe longitudinal 51 de l'applicateur de la position rétractée à la position étendue.In the retracted position, visible in particular to figures 2A and 3A , the hairs extend entirely inside the body 1. In the extended position visible in particular to the figures 2B and 3B , the bristles 3 protrude out of the body with reference to the radial direction to the axis 51, over a major part of the length of each bristle. It can therefore be seen that the applicator is arranged so that each free end of the bristle follows a path transverse or perpendicular to the longitudinal axis 51 of the applicator from the retracted position to the extended position.

Pour faire passer les poils de la position rétractée à la position étendue, l'actionneur 4 subit une translation rectiligne suivant son axe longitudinal dans le sens T indiqué sur la figure 1. Pour faire le changement inverse, il subit une translation rectiligne suivant son axe longitudinal dans le sens S.To move the bristles from the retracted position to the extended position, the actuator 4 undergoes a rectilinear translation along its longitudinal axis in the direction T indicated on the figure. figure 1 . To make the reverse change, it undergoes a rectilinear translation along its longitudinal axis in the S direction.

Dans la position rétractée, le bourrelet 13 se trouve nettement en retrait de la face externe du corps, dans ce dernier. L'extrémité libre du poil se trouve dans ce mode de réalisation au même niveau que cette face. Un volume libre est donc ménagé dans l'alvéole au-dessus du bourrelet et autour du poil, volume qui présente une forme générale de manchon. Ce volume libre est destiné à être chargé en produit de maquillage comme on le verra plus loin.In the retracted position, the bead 13 is clearly set back from the outer face of the body, in the latter. The free end of the bristle is in this embodiment at the same level as this face. A free volume is therefore provided in the cell above the bead and around the pile, which volume has the general shape of a sleeve. This free volume is intended to be loaded with makeup product as will be seen below.

Dans la position étendue, illustrée par exemple à la figure 4B, le bourrelet s'étend en saillie de la face du corps. Le volume de produit de maquillage qui remplissait le volume de l'alvéole situé au-dessus du bourrelet a donc été emporté tout entier et se trouve maintenant intégralement à l'extérieur du corps. Dans la position étendue, les poils de chaque groupe se trouvent tout entiers dans le même plan perpendiculaire à l'axe 51, comme illustré sur la figure 4A. L'extrémité de l'actionneur vient alors se loger dans un évidement central 38 du chapeau.In the extended position, shown for example on figure 4B , the bead extends in protrusion of the face of the body. The volume of makeup product which filled the volume of the cell located above the bead has therefore been washed away entirely and is now entirely outside the body. In the extended position, the bristles of each group lie entirely in the same plane perpendicular to the axis 51, as shown in figure figure 4A . The end of the actuator then comes to be housed in a central recess 38 of the cap.

En position rétractée, les poils ont une forme en « S » présentant deux coudes. Cela présente l'avantage de ne pas nécessiter la sortie des poils de leur alvéole lorsqu'ils sont en position rétractée et de diminuer l'espace nécessaire au rangement de l'applicateur dans l'étui. À cette fin, l'espace central des disques est prévu pour être suffisamment grand pour recevoir le tronçon d'extrémité interne des poils qui est couché parallèlement à l'axe 51.In the retracted position, the bristles have an "S" shape with two bends. This has the advantage of not requiring the bristles to come out of their socket when they are in the retracted position and of reducing the space required for storing the applicator in the case. To this end, the central space of the discs is provided to be large enough to receive the inner end section of the bristles which is lying parallel to the axis 51.

Le mécanismeThe mechanism

Nous allons maintenant présenter le mécanisme qui permet de commander la sortie des poils 3 du corps 1 de la brosse 11 et la sortie de cette dernière hors de l'étui. Ce mécanisme comprend un sous-ensemble de pilotage 36. Ce dernier comprend notamment un guide 20, un poussoir 25, un ressort 27, un canon d'entrée/sortie de la brosse 26 et une aiguille 9.We will now present the mechanism which makes it possible to control the exit of the bristles 3 from the body 1 of the brush 11 and the exit of the latter from the case. This mechanism comprises a control sub-assembly 36. The latter comprises in particular a guide 20, a pusher 25, a spring 27, an inlet / outlet barrel of the brush 26 and a needle 9.

On a vu que la partie d'extrémité distale de l'actionneur 4 était reliée rigidement aux poils. L'autre extrémité, proximale, de l'actionneur est rigidement fixée à une extrémité distale d'une aiguille rectiligne centrale 9 du sous-ensemble de pilotage 36, comme illustré à la figure 5C notamment.It has been seen that the distal end part of the actuator 4 was rigidly connected to the bristles. The other end, proximal, of the actuator is rigidly fixed to a distal end of a central rectilinear needle 9 of the piloting sub-assembly 36, as illustrated in FIG. figure 5C notably.

L'aiguille 9 est liée rigidement par son extrémité proximale à l'extrémité distale d'un poussoir cylindrique creux 25 comme le montre la figure 10. Cette liaison peut par exemple être effectuée par vissage.The needle 9 is rigidly linked by its proximal end to the distal end of a hollow cylindrical pusher 25 as shown in Fig. figure 10 . This connection can for example be carried out by screwing.

On forme ainsi un équipage de plusieurs pièces, à savoir le poussoir 25, l'aiguille 9 et l'actionneur 4, rigidement liées entre elles et coulissant ensemble le long de l'axe 51 par rapport à l'étui.A team of several parts is thus formed, namely the pusher 25, the needle 9 and the actuator 4, rigidly linked together and sliding together along the axis 51 relative to the case.

Le sous-ensemble comprend en outre un canon 26 formé par une pièce de forme générale cylindrique creuse montée coulissante suivant l'axe 51 d'une part par rapport à l'étui, d'autre part par rapport à l'aiguille 9 sur laquelle elle est enfilée.The sub-assembly further comprises a barrel 26 formed by a part of generally hollow cylindrical shape mounted to slide along the axis 51 on the one hand relative to the case, on the other hand relative to the needle 9 on which it is strung on.

Un ressort 27 est interposé suivant la direction axiale entre le canon 26 et le poussoir 25 et enfilé sur l'aiguille 9. Il est en butée par son extrémité distale contre un épaulement d'une extrémité proximale du canon 26 et par son extrémité proximale contre l'extrémité distale du poussoir 25.A spring 27 is interposed in the axial direction between the barrel 26 and the pusher 25 and threaded onto the needle 9. It abuts by its distal end against a shoulder of a proximal end of the barrel 26 and by its proximal end against the distal end of the pusher 25.

Le mécanisme comprend également un guide 20 formé lui aussi par une pièce creuse de forme générale cylindrique. Cette pièce est ouverte à son extrémité distale. Elle est également ouverte de façon à présenter deux échancrures latérales allongées 54 parallèles à l'axe 51 et s'étendant en regard l'une de l'autre. Cette pièce est rigidement fixée à la partie mobile 47 de l'étui. Par conséquent, quand on manoeuvre la partie 47, on manoeuvre le guide 20.The mechanism also comprises a guide 20 also formed by a part hollow of generally cylindrical shape. This part is open at its distal end. It is also open so as to present two elongated lateral notches 54 parallel to the axis 51 and extending opposite one another. This part is rigidly fixed to the movable part 47 of the case. Therefore, when we operate part 47, we operate guide 20.

Le poussoir 25 comprend à son extrémité proximale deux reliefs 35 aptes à être reçus dans les échancrures 54 du guide et à coulisser dans celles-ci pour guider le poussoir par rapport au guide.The pusher 25 comprises at its proximal end two reliefs 35 adapted to be received in the notches 54 of the guide and to slide therein to guide the pusher relative to the guide.

Ce sous-ensemble de pilotage est disposé à l'intérieur d'un tube 19 comme représenté aux figures 9 et 10. Le tube, visible à la figure 9, est un tube cylindrique dont une extrémité proximale se situe au niveau du guide 20 et l'extrémité distale au niveau d'une extrémité distale de l'étui présentant un orifice de sortie 17 de l'applicateur.This piloting sub-assembly is arranged inside a tube 19 as shown in figures 9 and 10 . The tube, visible at the figure 9 , is a cylindrical tube, a proximal end of which is located at the level of the guide 20 and the distal end at the level of a distal end of the case having an outlet orifice 17 of the applicator.

Sur la face intérieure de sa portion située à proximité du guide, le tube 19 présente un double filet hélicoïdal 33 formant une rainure sur la face interne du tube. Le filet présente deux tronçons successifs 55, 56 suivant l'axe 51 ayant deux pas différents. Le premier tronçon en partant de l'extrémité proximale du tube présente ainsi un premier pas et le second un second pas plus faible que le premier pas. Les reliefs 35 du poussoir présentent un téton 42 qui forme saillie à leur surface. Ces tétons sont aptes à parcourir les deux tronçons successifs 55, 56 du double filet 33 du tube 19.On the inner face of its portion located near the guide, the tube 19 has a double helical thread 33 forming a groove on the inner face of the tube. The thread has two successive sections 55, 56 along the axis 51 having two different pitches. The first section starting from the proximal end of the tube thus has a first pitch and the second a second pitch smaller than the first pitch. The reliefs 35 of the pusher have a stud 42 which protrudes on their surface. These studs are able to travel through the two successive sections 55, 56 of the double thread 33 of the tube 19.

Le tube 19 présente dans une portion médiane du tube un relief annulaire interne 29 formant une butée pour l'extrémité proximale 38 du canon 26.The tube 19 has in a middle portion of the tube an internal annular relief 29 forming a stop for the proximal end 38 of the barrel 26.

Le tube 19 présente au moins une ouverture, et de préférence deux ouvertures radiales 30 se situant au niveau de son extrémité distale à proximité de l'orifice de sortie 17. Les deux ouvertures sont diamétralement opposées l'une à l'autre de part et d'autre de l'axe.The tube 19 has at least one opening, and preferably two radial openings 30 located at its distal end near the outlet orifice 17. The two openings are diametrically opposed to each other on both sides. other side of the axis.

La portion d'extrémité distale du tube présente une section évasée plus grande que sa section dans le reste du tube. Cette section plus grande permet le positionnement d'une valve 18.The distal end portion of the tube has a larger flared section than its section in the rest of the tube. This larger section allows the positioning of a valve 18.

Comme on peut le voir sur les figures 11A à 12C, le tube 19 est disposé dans l'étui. L'espace périphérique annulaire restant autour du tube est occupé par un réservoir de mascara 21.As can be seen from figures 11A to 12C , the tube 19 is placed in the case. The annular peripheral space remaining around the tube is occupied by a mascara reservoir 21.

Le réservoirThe reservoir

Le réservoir de mascara 21 ou cartouche présente ainsi une forme de manchon cylindrique à section annulaire circulaire. Il comprend une paroi externe 58 et une paroi interne 59 coaxiales. Le mascara 43 se trouve exclusivement entre ces deux parois et du côté de la face externe 60 de la paroi interne. Cette face est en regard de la face interne de la paroi externe, en l'absence de produit dans le réservoir. Le réservoir est rigidement fixé à la partie fixe 48 de l'étui.The mascara reservoir 21 or cartridge thus has the shape of a cylindrical sleeve with a circular annular section. It comprises an outer wall 58 and an inner wall 59 coaxial. The mascara 43 is found exclusively between these two walls and on the side of the external face 60 of the internal wall. This face is opposite the face internal of the external wall, in the absence of product in the tank. The reservoir is rigidly fixed to the fixed part 48 of the case.

Comme on va le voir, la brosse 11 n'est pas en contact avec le produit 43 du réservoir et ne s'étend pas dans ce dernier lorsque la brosse n'est pas utilisée.As will be seen, the brush 11 is not in contact with the product 43 from the reservoir and does not extend into the latter when the brush is not in use.

Le réservoir 21 présente ici deux ouvertures 28 situées à l'extrémité distale du réservoir qui se trouve à proximité de l'orifice de sortie 17. Ces ouvertures coïncident avec les deux ouvertures similaires 30 du tube intérieur. Ces ouvertures ont une orientation radiale en direction de l'axe 51.The reservoir 21 here has two openings 28 located at the distal end of the reservoir which is located near the outlet orifice 17. These openings coincide with the two similar openings 30 of the inner tube. These openings have a radial orientation towards the axis 51.

La sortie du mascara du réservoir peut être réalisée de plusieurs manières. En l'espèce, le mascara est maintenu sous pression à l'intérieur du réservoir de sorte que, lorsqu'au moins une ouverture du réservoir est ouverte cette pression fasse sortir le mascara à travers cette ouverture.The exit of the mascara from the reservoir can be carried out in several ways. In this case, the mascara is kept under pressure inside the reservoir so that, when at least one opening of the reservoir is open, this pressure causes the mascara to exit through this opening.

Ici, comme présenté aux figures 11A à 13, le mascara est maintenu sous pression dans le réservoir par un mécanisme à piston 22 et ressort 23. Le ressort et le piston ont une forme annulaire similaire à celle du réservoir dans lequel ils sont logés. Le piston 22 est en contact avec les parois du réservoir. Il est mobile à coulissement à l'intérieur du réservoir suivant la direction de l'axe 51. Le ressort 23 est en appui par son extrémité distale contre le piston et par son extrémité proximale contre un bouchon placé contre l'extrémité proximale du réservoir. Au fur et à mesure que le réservoir se vide de mascara, le piston se déplace en direction de l'extrémité distale du réservoir sous l'effet du ressort.Here, as presented to figures 11A to 13 , the mascara is maintained under pressure in the reservoir by a piston mechanism 22 and spring 23. The spring and the piston have an annular shape similar to that of the reservoir in which they are housed. The piston 22 is in contact with the walls of the reservoir. It is movable to slide inside the reservoir in the direction of the axis 51. The spring 23 bears by its distal end against the piston and by its proximal end against a stopper placed against the proximal end of the reservoir. As the reservoir empties of mascara, the plunger moves towards the distal end of the reservoir under the effect of the spring.

Le dispositif comprend en outre une valve 18 visible notamment à la figure 7. Cette valve présente une forme générale cylindrique et possède au moins une ouverture radiale 45 située au niveau de sa paroi latérale, de préférence plusieurs. Elle est montée coulissante par rapport au tube 19 en étant logée dans son tronçon évasé. La valve présente un logement cylindrique d'axe 51 en son centre, apte à être traversé par la brosse 11.The device further comprises a valve 18 visible in particular at the figure 7 . This valve has a generally cylindrical shape and has at least one radial opening 45 located at its side wall, preferably several. It is mounted to slide relative to the tube 19 while being housed in its flared section. The valve has a cylindrical housing with an axis 51 in its center, capable of being traversed by the brush 11.

La valve peut passer d'une position proximale à une position distale. La position proximale de la valve 18 est une position fermée dans laquelle les ouvertures 45 de la valve ne sont pas en coïncidence avec celles du réservoir 21 et du tube 19. La position distale est une position ouverte dans laquelle les ouvertures de la valve sont en coïncidence avec celles du réservoir et du tube.The valve can move from a proximal position to a distal position. The proximal position of the valve 18 is a closed position in which the openings 45 of the valve do not coincide with those of the reservoir 21 and of the tube 19. The distal position is an open position in which the openings of the valve are in contact. coincidence with those of the reservoir and the tube.

La valve possède une ou plusieurs lamelles élastiques hélicoïdales 46 d'axe 51 de rappel de la valve en position proximale. Les lamelles présentent une extrémité proximale fixée à la face distale du corps de la valve et une extrémité distale libre en appui axial contre le bord de l'orifice 17. Ces lamelles permettent ainsi d'arrêter la distribution de mascara à partir du réservoir une fois que l'applicateur de mascara est sorti de l'étui.The valve has one or more elastic helical lamellae 46 with an axis 51 for returning the valve to the proximal position. The lamellae have a proximal end fixed to the distal face of the valve body and a free distal end bearing axially against the edge of the orifice 17. These lamellae thus make it possible to stop the distribution of mascara from the reservoir once. that the mascara applicator is taken out of the holster.

Le coulissement de la valve de la position fermée à la position ouverte a lieu par friction sous l'effet d'un mouvement de la brosse pour la sortie de la brosse hors de l'étui. Le coulissement en sens inverse a lieu sous l'effet des lamelles de rappel.The sliding of the valve from the closed position to the open position takes place by friction under the effect of a movement of the brush for the exit of the brush from the case. Sliding in the opposite direction takes place under the effect of the return slats.

FonctionnementFunctioning

L'applicateur fonctionne comme suit.The applicator works as follows.

On suppose que l'article est dans la configuration des figures 1 et 11A, la brosse 11 se trouvant tout entière dans l'étui, en position rentrée, ses poils 3 étant tout entiers dans le corps 1, en position rétractée donc.It is assumed that the article is in the configuration of figures 1 and 11A , the brush 11 being entirely in the case, in the retracted position, its bristles 3 being entirely in the body 1, in the retracted position therefore.

On fait tourner la partie mobile 47, et donc le guide 20, par rapport à la partie fixe 48 autour de l'axe 51.The movable part 47, and therefore the guide 20, is rotated relative to the fixed part 48 about the axis 51.

Les tétons 42 des reliefs 35 de guidage du poussoir circulent alors dans la première partie proximale du filet 33 du tube 19. Comme ces reliefs sont bloqués à rotation dans les échancrures 54 du guide 20, cela entraîne le coulissement du poussoir 25 suivant la direction de l'axe 51 dans le sens T.The studs 42 of the pusher guide reliefs 35 then circulate in the first proximal part of the thread 33 of the tube 19. As these reliefs are locked against rotation in the notches 54 of the guide 20, this causes the sliding of the pusher 25 in the direction of axis 51 in the T direction.

Le poussoir 25 entraîne avec lui en coulissement, sous l'effet du ressort 27, le canon 26, l'aiguille 9, l'actionneur 4 et la brosse 11. Ce coulissement entraîne la sortie de l'applicateur hors du corps de l'étui, comme sur la figure 11B. Tous les disques de la brosse sont alors hors de l'étui. Le coulissement se poursuit jusqu'à ce que l'extrémité proximale 38 du canon 26 arrive en butée axiale contre l'épaulement 29 du tube 19.The pusher 25 drives with it in sliding, under the effect of the spring 27, the barrel 26, the needle 9, the actuator 4 and the brush 11. This sliding causes the applicator to exit from the body of the. case, as on the figure 11B . All the brush discs are then out of the case. The sliding continues until the proximal end 38 of the barrel 26 comes into axial abutment against the shoulder 29 of the tube 19.

Au cours du mouvement préalable à cette sortie, la brosse 11 entraîne par friction le coulissement de la valve 18 au contact du corps de la brosse pénétrant dans la valve qui passe donc de la position fermée à la position ouverte. On obtient ainsi la mise en coïncidence des ouvertures 28, 30, 45 du réservoir 21, du tube 19 et de la valve 18.During the movement prior to this exit, the brush 11 drives by friction the sliding of the valve 18 in contact with the body of the brush entering the valve which therefore passes from the closed position to the open position. In this way, the openings 28, 30, 45 of the reservoir 21, of the tube 19 and of the valve 18 are brought into coincidence.

Sous l'effet de la pression exercée par le mécanisme ressort-piston, le mascara sort du réservoir à travers ses deux ouvertures 28, passe par le tube et la valve et se répand dans les volumes libres de certaines des alvéoles 37 de la brosse. Il s'agit des alvéoles qui sont exposées aux flux de produit lors du passage de la brosse devant les ouvertures. Les autres alvéoles ne sont pas chargées en produit.Under the effect of the pressure exerted by the spring-piston mechanism, the mascara leaves the reservoir through its two openings 28, passes through the tube and the valve and spreads into the free volumes of some of the cells 37 of the brush. These are the cells which are exposed to the flow of product when the brush passes in front of the openings. The other cells are not loaded with product.

Après la mise en butée, sachant que l'utilisateur continue à faire tourner la partie mobile de l'étui, le poussoir 25 continue à coulisser dans le sens T, les tétons 42 des reliefs de guidage 35 du poussoir parcourant maintenant le deuxième tronçon distal du filet du tube 19. Ce coulissement a donc lieu en comprimant le ressort 27. Le poussoir entraîne l'aiguille 9 et l'actionneur 4 suivant l'axe, provoquant ainsi le passage des poils 3 de la position rétractée à l'intérieur du corps de l'applicateur à la position étendue, en saillie à l'extérieur du corps de l'applicateur comme sur la figure 11C.After the abutment, knowing that the user continues to rotate the movable part of the case, the pusher 25 continues to slide in the direction T, the pins 42 of the guide reliefs 35 of the pusher now traversing the second distal section of the thread of the tube 19. This sliding therefore takes place by compressing the spring 27. The pusher drives the needle 9 and the actuator 4 along the axis, thus causing the bristles 3 to pass from the retracted position inside the applicator body in the extended position, protruding outside the applicator body as on the figure 11C .

Lors de ce fonctionnement, il est notable que le ressort 27 n'est pas sollicité lors de la première partie du mouvement, c'est-à-dire jusqu'à ce que le canon 26 arrive en butée contre l'épaulement 29 du tube. Cette première partie du mouvement correspond à la partie où les tétons des reliefs parcourent la première partie du filet 33 du tube (la partie ayant le pas le plus grand). Cette première partie du mouvement correspond à la sortie de la brosse hors du corps de l'applicateur.During this operation, it is notable that the spring 27 is not biased during the first part of the movement, that is to say until the barrel 26 comes into abutment against the shoulder 29 of the tube. . This first part of the movement corresponds to the part where the studs of the reliefs traverse the first part of the thread 33 of the tube (the part having the greatest pitch). This first part of the movement corresponds to the exit of the brush from the body of the applicator.

Le ressort 27 est ensuite comprimé dans la seconde partie du mouvement, celle-ci se faisant par le parcourt des tétons des reliefs dans le deuxième tronçon du filet 33 du tube, afin de permettre aux poils de l'applicateur de sortir du corps de l'applicateur.The spring 27 is then compressed in the second part of the movement, the latter being done by traversing the studs of the reliefs in the second section of the net 33 of the tube, in order to allow the bristles of the applicator to come out of the body of the tube. 'applicator.

Au cours de la sortie des poils, les poils associés aux alvéoles chargées en produit emportent avec leurs bourrelets le mascara initialement chargé dans les alvéoles. C'est donc le tronçon d'extrémité libre des poils qui est chargé en mascara et non l'intégralité de ceux-ci. Notamment, la partie de la brosse s'étendant entre le bourrelet et le corps de la brosse n'est pas chargée en mascara ou bien en est chargée d'une très faible quantité. On a donc réalisé un chargement de la brosse avec la quantité de mascara juste nécessaire pour effectuer le maquillage.During the exit of the bristles, the bristles associated with the cells loaded with product carry with their beads the mascara initially loaded in the cells. It is therefore the free end section of the bristles which is loaded with mascara and not all of them. In particular, the part of the brush extending between the bead and the body of the brush is not loaded with mascara or else is loaded with a very small amount. The brush was therefore loaded with the amount of mascara just necessary to carry out the makeup.

Dans ce mode de réalisation, les ouvertures du tube 19 et celles du réservoir ne s'étendent que sur une partie de la circonférence de ceux-ci. Cela entraîne que ce sont certaines seulement des alvéoles 37 qui sont chargées en mascara lors du passage de la brosse, certaines des alvéoles n'étant pas chargées à cette occasion. Cela constitue un mode de réalisation préféré de l'invention. En effet, cela permet que les poils qui ne sont pas chargés en mascara étalent le mascara qui aura été déposé sur les cils par les poils qui ont été chargés en mascara. Les poils non chargés en mascara initialement permettent un meilleur étalement de celui-ci le long des cils. Au cours du maquillage des cils, le mascara est transféré depuis les poils initialement chargés vers les cils, et aussi vers les poils non chargés initialement, puis de ceux-ci vers les cils. Normalement, la quantité de mascara restant sur la brosse après le maquillage est minime.In this embodiment, the openings of the tube 19 and those of the reservoir extend only over a part of the circumference thereof. This means that only some of the cells 37 are loaded with mascara during the passage of the brush, some of the cells not being loaded on this occasion. This constitutes a preferred embodiment of the invention. This is because this allows the bristles which are not loaded with mascara to spread the mascara which will have been deposited on the eyelashes by the bristles which have been loaded with mascara. The hairs not loaded with mascara initially allow better spreading of the latter along the eyelashes. During the makeup of the eyelashes, the mascara is transferred from the initially loaded bristles to the eyelashes, and also to the initially unloaded bristles, then from the latter to the eyelashes. Normally, the amount of mascara left on the brush after makeup is minimal.

On observe en particulier que la brosse est chargée en mascara avant sa sortie intégrale hors de l'étui et également avant la sortie des poils hors du corps de la brosse. Chacune de ces caractéristiques présente ses propres avantages. Le chargement de la brosse avant la sortie de l'étui évite de mettre le contenu du réservoir directement en contact avec l'air libre ambiant, ce qui réduit les risques de séchage. Le chargement de la brosse dans les alvéoles avant la sortie des poils réduit la quantité de produits à déposer sur la brosse.It is observed in particular that the brush is loaded with mascara before its full exit from the case and also before the bristles exit from the body of the brush. Each of these characteristics has its own advantages. Loading the brush before taking it out of the case prevents the contents of the reservoir from coming into direct contact with the ambient air, which reduces the risk of drying out. Loading the brush into the cells before the bristles come out reduces the amount of product to be deposited on the brush.

La quantité de mascara qui sera chargé sur la brosse dépend pour une bonne part du volume libre des alvéoles et donc de la configuration de celle-ci et des poils.The amount of mascara which will be loaded onto the brush depends largely on the free volume of the cells and therefore on the configuration of the latter and of the bristles.

Bien entendu, on pourra apporter à l'invention de nombreuses modifications sans sortir du cadre de celle-ci.Of course, numerous modifications can be made to the invention without departing from the scope thereof.

On pourra ainsi modifier la configuration de l'étui. Par exemple, l'invention pourrait être mise en oeuvre avec un étui comprenant un capuchon amovible. On pourra alors prévoir que l'applicateur est fixé à demeure au capuchon.We can thus modify the configuration of the case. For example, the invention could be implemented with a case comprising a removable cap. Provision can then be made for the applicator to be permanently attached to the cap.

On peut prévoir que le réservoir est amovible c'est-à-dire qu'il peut être ôté facilement de l'étui lorsque le réservoir est vide pour le remplacer par un réservoir plein ou bien le recharger en produit.Provision can be made for the reservoir to be removable, that is to say that it can be easily removed from the case when the reservoir is empty in order to replace it with a full reservoir or else to reload it with product.

On pourrait prévoir que chaque couronne d'alvéoles comprend un nombre différent d'alvéoles que celui décrit plus haut. Il pourrait en être de même pour chaque groupe de poils.Provision could be made for each ring of cells to include a different number of cells than that described above. It could be the same for each group of hairs.

L'applicateur ne sera pas nécessairement une brosse. Il pourra être un peigne.The applicator will not necessarily be a brush. It could be a comb.

De nombreuses caractéristiques de l'article peuvent être mises en oeuvre indépendamment les unes des autres. En particulier, on pourra mettre en oeuvre indépendamment les uns des autres les trois aspects suivants :

  • le montage mobile des protubérances de l'applicateur entre une position rétractée et une position étendue dans laquelle elles s'étendent davantage à l'extérieur du corps de l'applicateur qu'en position rétractée,
  • la configuration du réservoir avec des parois externe et interne, dans laquelle le produit se trouve exclusivement du côté d'une face de la paroi interne orientée vers la paroi externe, et
  • le montage mobile de l'applicateur par rapport à l'étui entre une position rentrée et une position sortie dans laquelle il s'étend davantage hors de l'étui qu'en position rentrée.
Many features of the article can be implemented independently of one another. In particular, the following three aspects can be implemented independently of one another:
  • the movable mounting of the protuberances of the applicator between a retracted position and an extended position in which they extend more outside the body of the applicator than in the retracted position,
  • the configuration of the tank with external and internal walls, in which the product is located exclusively on the side of a face of the internal wall oriented towards the external wall, and
  • the movable mounting of the applicator relative to the case between a retracted position and an extended position in which it extends more out of the case than in the retracted position.

Dans un mode de réalisation particulier, on peut facilement démonter l'article pour remplacer la brosse par une autre brosse. Cette caractéristique est particulièrement avantageuse puisqu'elle permet aux utilisateurs de faire des économies substantielles en n'ayant pas à acheter l'article complet une fois la brosse usée.In a particular embodiment, the article can easily be dismantled to replace the brush with another brush. This feature is particularly advantageous since it allows users to make substantial savings by not having to purchase the complete article after the brush is worn out.

La présence de la valve est facultative. En effet, la distribution de produit peut être arrêtée en donnant une forme appropriée à l'intérieur de l'article. arrêtée en donnant une forme appropriée à l'intérieur de l'article.The presence of the valve is optional. Indeed, the product dispensing can be stopped by giving an appropriate shape to the interior of the article. stopped by giving an appropriate shape to the interior of the article.
